PORATION 0F NEW JERSEY OF PATERSON, NEW JERSEY, A COR- FRENCH-IBINDINGSTRAIGHTEN IN G AN D CEMENTING MACHINE Application filed March 5,

This invention relates to improvements in French binding machines andthe invention is herein illustrated as embodied in a-inachine forrubbing out or straightening a fabric French binding strip attached to amarginal portion of a shoe upper and applying a coating of cement to themargin of the upper and to the binding strip.

In the manufacture of certain classes of Work, especially ivomens shoes,it is desired to bind the edges of the upper with a fabric strip inorder to produce so-called French binding or a French edge. In thisWork, a fabric binding strip is secured to the outer face of theupper ina position ,Wholly overlying the upper b v means of a row of stitchinglocated close to the margin of the upper. After the binding has beenstitched to the material, the French edge is formed by the threedistinct steps of, first, rubbing out or straightening the fabric stripto leave the free'portion of the binding extending out from the edge ofthe piece of Work to Which the binding is attached in substantially theplane of that piece of Work, second, the application of a coating of,cement to the inner face of the material along its margin and to theface of the straightened binding strip which is to be folded againstt-he work, and, third, the folding of the free portion of the strip overthe edge of the piece of Work and pressing it into place to attach it tothe inner face of the Work.

In carrying out the first of these steps the strip must be wipedA outrather vigorously until the stitches smile, that is, until they can beplainly seen.l Some difficulty has been experienced in performing thisoperation effectively upon pieces of Work of delicate` material Withoutdamaging the material, as by scutling the surface of the material,especially at .points such as at seams Where the thickness of the Workisconsiderably greater than elsewhere. The second step of the operationalso involves some ditlicultiesfor the reason that thestraightenedbinding strip, being attached to the outer surface of thepiece of work, necessarily lies in a different v plane from-the innerface of the work which is to be coated with cement. It is not easy,

therefore, to apply the proper coating of cement to both of these partsand to have the machine arranged so that it may be utilized ing stripand to apply a coating of cement to the Work.

. feo'- The danger of scutfing the Work `is eccenq-VA 5 tuated by thefact that machines of thistype f customarily employ positive means forfeed-xv ing or advancing the Work past a rotary straightening disk, thetendency of which is to retard the Work. An important feature of thepresent invention resides in the provision of a driven Wiper disk whichacts to straighten v the binding strip and has its peripheral portionconstructed and arranged to assist the feeding means in advancing theWork instead of retarding it. lVhem as in the illustrated machine, thefeeding means is driven frictionally to assist the operator in handlingthe ivork and to avoid the possibility of damage to the surface of thework, then this construction of the Wiper disk is of even greaterimportance because of the fact that it allows lighter engagement of thefriction driving means with -the Work'feeding mechanism because theWiperdisk is constantly helping the progress of the Work. Thus themovement of the Work engaging rolls may be more readily interrupted incase of abnormal con-- ditions instead 'of being forced to scuf thework.

The application of cement to the margin of the Work and toV the bindingstrip may best be effected bymeans of a supporting roll underlying theWork and dipping in a suitable receptacle. This roll by reason ofproperly formed peripheral surface assists to some extent in the feedingof the Work and also co-operates in gripping and feeding the Work, witha presser or feed roll engaging the upper surface of the leather towhich the binding strip is attached. These parts, however, make noprovision for holding the binding strip against the cement roll. Stillanother feature of the invention resides inthe provision of pressermeans constructed and arranged to force the extended portion of thebinding strip toward the cement applying and supporting roll so thatsubstantially the whole width of the binding strip will become coatedwith cement. Such an arrangement overcomes `the natural tendency of thebinding strip to hold itself away from the cement on the supportingroll. construction the auxiliary presser means comprises a'wire loopreceived in a groove in the presser roll and pressing against thebinding strip in a relation to the margin of the piece which may bevaried to suit the needs of differentclasses of work and to meet thewishes of various operators.

As wasinentioned above, the use of such a machine on more delicateleathers presents a particular problem when thicker parts of the work,such as are caused by seams, are encountered and in order to avoid andovercome Athis difficulty, the illustrated machine has structed andarranged to allow the operator to relieve the pressure lon one of therolls here, the wiper disk, as a thicker portion of the work is reached.n'

Still other features f the invention relating to the organization of theillustrated machine and also to the construction of an adjustable edgegage with which the machine is provided are set forth in the followingdescription and are pointed out in the claims.

The illustrated machine is arranged to apply a coating of` cement to themargin of the inner surface of a leather work piece 11 (Fig. 7) and toan attached binding strip 13 on a piece of French bindin work as thebindin strip is straightened. French binding wor 1s used largely-for theuppers of shoes and in In the illustrated of an upper such as a vamp ora quarter, the edge of which is to be finished by being bound with afabric binding strip 13 which is first superposed on the leather workpiece in a position wholly overlying the piece of work so that theperipheries of the two coincide and is attached in that position bymeans of a row of stitching close to the edge of the u per, prior tobeing straightened, coated wit cement and folded around'the edge of theupper for attachment to the inner face thereof.

The machine is provided with a cement receptacle 10 having a cover 15.This receptacle is in the formv of an arm extending outwardly from apedestal base 12 parallel to the front of a bench on which the machineis mounted, and cement is maintained at a constant level within thisreceptacle 10 by an inverted bottle 14 which, by barometric action, suplies cement to the receptacle 10 as it is used fiom the latter. Theinverted bottle 14 has a threaded neck 16 (Fig. 9) on which there ismounted a collar 18 which is used to support it upon the receptacle 10,and adjustably to determine the position of the bottom end 20 Vof theneck of the bottle. The receptacle 10 is provided (Fig. 1) with a drainopening normally closed by a cover 19, and in the cover 15 there isprovided a swinging cover 2 1 fora dip opening to allow the operator toremove a small quantity of cement formanual application to the work.

. most cases the work piece 11 will be a portion A cement applying roll22 having a roughened surface is positioned in the open outer end of thereceptacle 10 and is mounted upon a shaft 24 carrying a gear 26 whichlmeshes with a gear 28 (Fig. 9) secured to the shaft of the drivingpulley 30. The detailed construction of this cement applying roll 22 hasnot been illustrated herein but it may be constructed as shown inLetters Patent ofthe United States No. 1,242,925, granted October 16,1917 upon the application of J ohii W. Cosgrove. In that patent, thereis shown a cement roll made of a plurality of disk-like sections whichare clamped together and some of which have peripheral ckets, whileothers have outwardly projecting teeth thereby more firmly to engage thework and to feed it along.

The shaft 24 of the cement roll asses through .bearing sleeves 32 and 34suitably supported in the casting of the receptacle 10 and in order thatthe cement may not work into the bearing surfaces between the shaft 24`and these sleeves 32 and 34 a removable cylindrical casing 36 has beenprovided which surrounds the shaft 24-and fits tightly and merges intoextensions upon the bearing sleeves 32 and 34, it being interlocke'dwith said sleeves by tongues such as is shown at 38 entering recesses insaid sleeves. This cylindrical casing is not onl advantageous alsoexcludes cement from contact with the drive shaft, and therebymaterially lightens the load unon the driving motor (not shown) at timeswhen the machine is started up after it has been idle over night or overthe weekend and cement has had an opportunity to dry out in thereceptacle. An additional means is provided for excluding cement fromthe bearing between the shaft 24 and the sleeve 32 in the form of a feltwasher 40 which is located in a recess at the end of the bearing sleeve32 closely adjacent to the end of the cement applying roll 22. The endof the receptacle 10 is provided with a removable cup-like cover 42 onwhich is mounted by means of dowel pins a thin scraper plate 44 (Fig. 4)for cleaning the outer end of the cement roll 22. A similar` scraperplate (not shown) is provided to clean the other end of the cement roll.The quantity of cement delivered to the work may be adjustablycontrolled b v means of a scraper 46 adjustably secured in position onthe top of th'e receptacle 10 by means ofv a screw 48. The lower surfaceof this scraper is approximately tangential to the cementing roll andits re'ar edge may be brought into the desired proximity to theperipheral surface of the cement applying roll and locked in thatposition by means of thescrew 48.

The scraper 46 is guided for front and back movement on the machinethereby adjustably to control the amount of cement delivered bythe roll22, by means of a depending rib '49 (Fig. 3) which is received in asomewhat deeper groove 51 in the upper surface of the receptacle 10. Asnoted above, the scraper is clamped in itsr adjusted position by meansof a screw 48 and, by reason of the fact that the rib 49 does not seatin the bottom of the groove 51, the pressure of the screw 48 tends tocorrect any slight inaccuracies in the manufacture of the parts and tobring the rear edge of the-scraper plate firmly into the desiredoperative relation to the cementing roll-along the entire length of saidedge.

It will be noted that the upper surface of the cement controlling'scraper 46 is cut away at 5() (Fig. 4') thereby to allow a closerapproach of the incoming work to the periphcry of the cement roll sothat the work may contact with a greater portion of the periphery beforeit is removed therefrom by means of a pick-olf fork 52 having a seriesof prongs which contact with the upper surface of the cement roll. Thisfork 52 is adjustably secured in position upon the rear side of thecement receptacle 10 by means of a screw 54.

Rubbing out or straightening of the binding strip 13, which has beenattached to the piece of leather 11 by means of arow of stitching withthe binding strip superposed on and wholly overlying the leather, isaccomplished by means of a driven wiper disk or roll 60 which is rotatedcounter-clockwise` as viewed in Figs. 3 and 7 (by means to bedescribed), to pull out or straightenl the binding strip till thestitches smilef7 so that the strip 13 eX- tends beyond the piece of work11 (Fig. 7) ready to be folded over the edge of the work and secured infolded position by the cement which is applied at the same time. It willbe noted that the Wiper disk 60 is provided with peripheral teeth, thecorners of which are chamfered on the front face as shown in Figs. 4 and'5, thereby to prevent scutiing. the

` work and possible damage to delicate leathers.

The peripheral teeth are cut somewhat saw fashion and the direction ofrotation of the disk 60 is such that the disk exerts a series of rapidwiping actions tending to pull out the binding until the fabric bindingstrip is given a permanent set in its straightened position so that acoating of cement may readily be applied to the under surface of thestrip and the strip made ready for the folding operation. In addition,the teeth 62 on the periphery of the wiper disk 60 are sections of ahigh pitch helical screw thread which is actuated in such a directionthat the rotation of the driven wiper disk assists in feeding the work.

The work, being fed into the machine in a direction away from theoperator, who stands in front of the machine as viewed in Fig. 1, issupported upon the outwardly extending arm 64 of an edge gage 65. Thisgage 65 has a gage surface 66 at the bottom of a throat or recess formedby means ofthe arm 64 and an overhanging finger 68. The forward edge ofsaid recess is relieved as appears in Figs. 3 and 6 to avoid abrasion ofthe edge of the work. Both the edge of thehleather 11 and the edge ofthe fabric strip 13 enter this recess with the further result that thecontinual pulling or lateral thrust of the wiper disk 60 in a directiontransverse to the direction of feeding movement holds the work againstthe gage rather than to dislodge the work from the gaging surface 66.The gage is supported by an integral block 70 slotted in a. directiontransversely of the direction of feeding movement and adjustably held inposition upon a sub-base 7 2 by a screw 7 4 so that the position of theedge of the work with respect to the cement roll 22 and the otheroperatingl parts laterally of the direction of work feeding movement maybe adjustably determined in accordance with the wishes of the operatorand the needs of any particular class of work.

It is also desirable at times to be able to adjustthe work gage to bringit` nearer to or farther away from the wiper disk. Such adjustment isprovided for by a slot 76 in the sub-base 72. The sub-base is receivedin a groove in the top of the receptacle 10 and may be held in adjustedposition by means of a.

screw 78. When the machine is being used for rather light, flimsyleathers, it is desirable to move the edge gage up quite close to thewiper disk 60, but when the machine is used for heavier leathers such aspatent leather, for example, it is not possible to operate the machinewith the edge gage as close to the wiper disk because of the resultingbend inthe work as it passes over the gage and then under the Wi erdisk.

s has already been brought out, the cement applyin roll 22 is moving inthe direction of feed of t e work and, therefore, helps to carry thework along and the teeth 62 on the wiper disk 60 are cut in such a waythat they also help the feed of the work. In order, however,

to provide for more positive work feeding movement, a knurled feed roll80 (Figs. 3, 4 and 7) (driven by means later described is providedwhich, as will also be explaine is pressed down against the surface ofthe leather 11 and presses it into engagement with the upper surface ofthe cement roll 22. The direction of rotation of this feed roll 80 isindicated by the arrow in Fig. 7 and its outer or left end, as viewed inFig. 3, is beveled to facilitate the use of the machine upon work partswhich are curved to form sharp corners or small recesses.

, Since thebinding strip 13 is .attached to the upper surface of theleather 11, considering thework in operative relation to the machine asshown in Fig. 7, the strip 13 obviously extends out from the leather ata level above the level of the lower surface of the leather 11. Itfollows, therefore, that the binding strip normally is above the cementroll and the application of a proper coating of cement to the bindingstrip isV hindered by this relation. In order to over" come thisdiiiculty, the feed roll 80 is proe vided with a peripheral groove 82which receives the looped lower end of a wire auxiliary presser member84 the upper end of which, as is more clearly shown in Fig. 4, is`

bent rearwardly at 85 and is supported by a screw stud 86. To hold thecurved lower end of this presser wire 84 in such a position that it willextend below the surface of the feed roll 80, the free outer end 88 ofthe wire is passed beneath a pin 90 which underlies the rearwardlyextending portion 85. By proper adjustment of the edgeL gage, thispresser wire 84 may be brought to bear on the strip at any pointtransversely of the width of the binding strip 13, depending upon theparticular character of the work and the desires of the operator,thereby exerting additional pressure upon the extended strip to which ispositioned toward the back of the machine and is arranged to support thewiper disk 60, and another lever 100 which is located nearer the frontvof the machine and is arranged to support the feed roll 80. The forwardlever 100 has at the left (as viewed in Fig. 1) a channeled arm 102which receives a drive shaft 104 for the feed roll 80, and at the righta iattened arm 106. The lever 98 has a similar channel-shaped arm 110 atthe left surrounding and supporting a drive shaft 118 for the wiper disk60 and also has a iattened arm 112 extending to the right to which atreadle rod 108 is connected, this arm 112 of the lever 98 being alsoprovided 114 for the reception of a stop screw 116 which is arranged tocontact with the arm 106 of the forward lever 100 after the treadle hasbeen slightly depressed, for a purpose which will later appear. A bridgepiece 120 secured to the upper end of the standards 92 and 94 isprovided with an extension to the left having a depending forked portion122 which receives and closely surrounds arms 102 and 110 and isprovided with recesses for the reception of springs 124 which bearagainst pins 126 resting upon the upper surfaces of the arms 102 and 110of the levers. Adjusting screws 128 are provided for varying the tensionof these springs. It will be potted that the arm 102 is provided with a130 to bring its upper surface at this particular point to the level ofthe upper.

The arrangement thus described, therefore,

provides for the holding of the operating tools 60 and 80 resiliently incontact with the work and allows the operator to depress the treadleconnected to the rod 108, sharply, to lift both rolls when it is desiredto enter a piece of work or only slightl so vthat the screw 116 does notcontact wit the arm 106 when it is desired thereby to lift the wiperdisk 60 merely enough to relieve the pressure of said wiper disk onthickened portions of the work such as are caused by seams or wrinkles.It will be understood that the fact that the wiper disk 60 is rotatedin'a plane substantially at right angles tothe feed of the work makes itimpossible for the disk automatically to climb over any thick portions,such as seams, and although the danger of scuiiing the surface of workat such places is minimized by reason of a friction drive for the wiperdisk, to be described later, still it is found advantageous to help thedisk to-pass over such thickened portions by lifting it noted. On theother hand, the rolling action of the feed roll 80 is such that itsnatural tendency/is to climb over any thickened portion of the work. Itis, therefore, unnecessary to lift the feed roll at the same time thatthe wiper disk is lifted and it is, of course advantageous to leave thefeed roll in en` gagement with the work so that the progress of the workwill not be interrupted.

The manner of supporting the wiper disk 60 in the outer end of the lever98 is illustrated in Figs. 3 and 4, from which it will be seen that thechanneled arm 11-0 of said lever is enlarged to provide depending arms132 (Fig. 4) which furnish bearings for a transverse stub shaft 134 uponwhich the disk 60 is mounted. Skew gears 136 interconnect the stub shaft134 and the shaft 118 which extends longitudinally through and isjournaled in the lever 98. At the further right end of the shaft 118 issecured a pinion 138 by means of which said shaft is driven.

At the left end of the arm 102 of the forward lever 100 is mounted ahorseshoe shaped bracket 142 which has a tongue and y groove connection144 (Fig. 4) with the upper side of said lever arm 102, and is securedin position thereon by means of screws 146 (Fig. 3). The feed roll 80 ismounted on a removable shaft 148 extending between the spaced lower armsof the horseshoe shaped bracket and provided at its right end with apinion 150. This pinion meshes with an intermediate gear 152 freelyrotatable upon a stud which extends between a depending portion of thelever arm 102 and one side -154 of the horseshoe shaped bracket and thisgear meshes with another pinion 156 se` cured to one end of the driveshaft 104. Near the other end of this shaft, there is provided a pinion160 (Fig. 1) which is loosely mounted thereon and meshes with the gear26 on the end of the cement roll shaft. The pinion 160 is integral withone plate or disk 162 of a friction drive, the other plate 164 of whichis integralwith another pinion 166 which is keyed to the shaft 104. Thepinion 166 mesheswith the pinion 138 on the end of the wiper disk shaftso that both the wiper disk 60 and the feed roll 80 are frictionallydriven from power supplied through the driving pulley 30. Provision ismade for adjusting athe tension on the disks 162, 164 by rotating aknurled n ut 168 which bears against a spring 170 resting in turn on theright side of the pinion 166 to hold the disks 162 and 164 in frictionalcontact. A cover plate 172 is detachably secured to the right end of the.frame to cover up this train of gears. l

Driving through the friction disks 162 and 164 is advantageous not onlybecause of the fact that parts of the machine are subject to accidentalcoating with cement which becomes dried on the machine and might,

except for the friction drive, cause breakage of parts in case anattempt were made to start the machine up before the dried cement wascleaned olf, but is also of substantial utility in preventing damage tothe work when the wiper disk encounters an unusually thick work portionor a wrinkle in the work. The` tension on this friction drive 162, 164,controlled by rotating the nut 168, is regulated in such a way that thedriving force applied is just sufficient to cause a steady progress ofthe work under normal conditions. It is also to be noted that thenatural feedretarding effect of a disk rotating transversely to thedirection of feed in contact with the surface of the work, such as thedisk 60, is overcome here by reason of the construction of the peripheryof said disk whereby it helps to feed the work. The

feeding tendency of the disk constructed as herein illustrated is asufcient help to the feeding action of the roll 80 so that the tensionon the friction drive for said roll 80 adjusted by means of the nut 168may be lessened below what would be needed in case there were no suchfeeding tendency. This is advantageous because it allows the machine tooperate properly upon the work vand at the same time requires lessresistance to interrupt the normal action of the wiper disk 60 or of thefeed roll 80 and, therefore, renders the machine less likely to damv agethe work.

Since there is danger that the wiper disk may become accidentally coatedwith cement a cleaner in the form of a piece of felt 174 is held incontact with the upper surface of the wiper disk. The felt 174 issupported in the desired position by a bracket 176 which is secured tothe upper surface of the lever arm byy screws 178. The bracket 176provides a pocket 'for the piece of cleaner felt 174 and athumb screw180 threaded in the upper side of said bracket is arranged to bearagainst a plate 182 which rests upon the upper surface of the cleanerfelt 174.

In the operation of the machine the operator, having applied power tothe driving pulley 30, depresses the treadle rod 108 sharply, thereby toseparate the treating rolls by liftlng both the wiper disk 60 and thefeed roll 80 away from the cement roll22 to facilitate the insertion ofa piece of Work, the edge of the work being brought against the gage'the overhangingA surface 66 and beneath finger 68 with the fabric strip13 turned over this finger in straightened position. The operator thenreleases the treadle and thev action of the wiper disk progressivelypulls out and straighten's the binding strip as the work is fed along-bythe combined action of the wiper disk, the cement roll 22 and the feedroll 80. The feed roll also serves as a presser roll, tending to effectproper engagement of the lower surface of the work with the uppersurface ign of the cement roll 22. In addition, the binding strip 13 isheld down against the cement roll by means of the presser wire 84:, theroll 80 and wire 84 insuring the application of a coatini of cement notonly to the under surface o the leather 11, but as Well to the bindingstrip 13 as indicated in Fig. 8. When a corner in the work is reached,the operator can readily shift thev work laterally around the gagingsurface 66 of the gage 65 because Hof the narrow bearing surface of thefeed roll 80 resultin from the fact that the roll 80 is beveled at itsouter end, while if a relatively thick work portion, such as thatresulting 15 from a seam or a wrinkle, is encountered, the

operator may, by a slight depression of the treadle rod 108, lift theWiper disk 60 to allow this thicker portion of the work to ,pass beneaththe wiper disk without injury vto delicate leathers or to the polishedsurface 0f a patent leather. By properly adjusting the nut 168 thetension on the frlction drive 162, f

164, may be adjusted to such a point that the wiper disk 60 and the feedroll 80 will operate with the greatest efficiency.
